Hi
sounds like an arp issue , thats what usually happens when the first ping is dropped then works , the default return time i think is only few seconds so if the far end takes longer to return the reply it will see it as a dropped ping , hard to tell woithout seeing some info but i would try set static arp and see if that makes a difference just for that ip
